Vultures have a remarkable ability to eat rotting carcasses that would be dangerous for other animals. Their digestive systems have adapted to allow them to safely consume meat infected with deadly bacteria. Vultures play an important role as nature’s cleanup crew by disposing of dead animals that would otherwise spread disease. What kind of teeth do vultures have? Vultures do not have teeth. Their beaks are designed for grasping and tearing food, not for chewing. Since they swallow food in large chunks, vultures have very acidic stomach acid to help break down meat and kill bacteria. How do vultures digest…

The evolution of photosynthetic organisms like plants, algae and some bacteria completely transformed the composition of Earth’s atmosphere and enabled the evolution of complex life. Before photosynthesis evolved, the atmosphere was very different – it contained virtually no oxygen, which is essential for humans and most animals to breathe. The emergence of photosynthesis filled the atmosphere with oxygen, paving the way for the evolution of complex multicellular organisms. Understanding what Earth was like before photosynthesis can provide insight into how life evolved and the co-evolution of life and atmosphere. The Early Atmosphere The early Earth atmosphere, before about 3.5 billion…
